CVE-2025-30417
📋 TL;DR
A memory corruption vulnerability in NI Circuit Design Suite's SymbolEditor allows attackers to execute arbitrary code or disclose information by tricking users into opening malicious .sym files. This affects users of NI Circuit Design Suite 14.3.0 and earlier versions who open untrusted symbol files.
💻 Affected Systems
- NI Circuit Design Suite
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with arbitrary code execution leading to complete control of the affected system, data theft, or lateral movement within the network.
Likely Case
Local privilege escalation or information disclosure from the current user's context, potentially leading to credential theft or further exploitation.
If Mitigated
Limited impact if proper application whitelisting and user training prevent execution of malicious files, with potential for application crash only.
🎯 Exploit Status
Exploitation requires social engineering to get users to open malicious .sym files. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: NI Circuit Design Suite 14.3.1 or later
Restart Required: Yes
Instructions:
1. Download the latest version from NI's official website. 2. Run the installer with administrative privileges. 3. Follow the installation wizard. 4. Restart the system after installation completes.
🔧 Temporary Workarounds
Restrict .sym file handling
windowsBlock or restrict opening of .sym files through application control policies or file association changes
User awareness training
allTrain users to only open .sym files from trusted sources and verify file integrity
🧯 If You Can't Patch
- Implement application whitelisting to prevent execution of unauthorized files
- Use network segmentation to isolate systems running vulnerable software from critical assets
